Clinical characteristics of patients with cardiogenic shock after out-of-hospital cardiac arrest (OHCA) compared to patients with cardiogenic shock without OHCA.
Article in Cardiology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCardiogenic shock (CS) often complicates out-of-hospital cardiac arrest (OHCA), contributing to high mortality despite therapeutic advances.
methodsThis study retrospectively analysed patients admitted to a tertiary centre between 2021-2024. The cohort of patients with CS was divided into two groups: OHCA with return of spontaneous circulation and non-OHCA.
resultsThe study included 280 patients with a median age of 69 (60-76) years, of whom 197 (70%) males. There were 46 (16%) patients in the OHCA group and 234 (84%) in non-OHCA. Acute coronary syndrome (ACS) was a more frequent cause of CS in the OHCA group: 36 (78%) vs. 113 (48%), p < 0.01. The OHCA patients were less likely to have hypertension (41% vs. 63%, p < 0.01), chronic heart failure (CHF) (41% vs. 62%, p < 0.01), and a history of percutaneous coronary intervention (11% vs. 29%, p < 0.01). The OHCA patients exhibited lower C-reactive protein) levels and higher levels of white blood cells. Despite distinct profiles, there was no significant difference in mortality between the study groups.
conclusionsPatients with OHCA and non-OHCA CS exhibited distinct clinical profiles, with ACS as the leading cause of OHCA and chronic conditions were more often diagnosed in non-OHCA cases. Similar mortality rates suggest improved OHCA management, emphasizing the need for extensive data collection to assess shock risk.
